LOOSE-FIBER CLEANER.

. Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed October 27, 1919. Serial No. 333,508.

To whom it may concern:

Be it known that I, JAoon A. SNYDER, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Loose- Fiber Cleaners,-of which the following is a specification. i

An object of my invention is to produce an improved device for removing all kinds of dirt, such as sticks, seed, stray, grit, and other foreign matter from loose fiber, such as wool, hair, cotton, etc., prior to its being passed through the machines in which yarn and other similar products are produced, in a more thorough manner than heretofore and with less waste ofthe cleaned fiber.

This and other objects are attained by'the device described in the following specification and illustrated in the accompanying drawings, in which Figure 1, is a longitudinal central vertical sectional view of a fiber cleaner embodying my invention.

. Fig. 2, is a sectional view taken upon line 22 of Fig. 1.

Fig. 3, is a sectional view taken upon line My improved cleaner has a cylindrical casing 1, which is supported at intervals at its sides by vertical supports 2 which are extended downwardly to form legs 3. At its top the casing is closed by a screen 4: held in place by a ring 5 which is secured to the upper ends of the supports2. A spider 6 which supports an axially located bearing 7 is also secured to the tops of the supports 2. This bearing 7 has a revolubly mounted fan 8 depending therefrom and surrounding the fan a cage 9 is provided. Cage 9 is constructed of a series of vertically positioned rods arranged annularly and secured at their upper ends in a ring 10 formed on the under side of the. spider 6. At their lower ends the rods are secured in the thickened upper periphery 11 of a deep ring 12 formed on a spider 13 to which the supports 2 are attached. In its upper end and in position to have the material to be cleaned, impinge fan 8,1 have provided a pipe 14: through which the material to be cleaned passes into the interior of cage 9.

Within the cage at its lower end I have placed a sheet metal deflecting cone or bafiie plate 15, the peak of which is axially located and the lower outer periphery of which is spaced from the inner edge of the upper periphery 11 of ring 12 in a suitable manner, as by a series of spaced braces 16 which rest upon the inner edge of the upper periphery 11 of. ring 12. Beneath this cone a screen 17 is located, having bearing upon lugs 18 upon the inner surface of ring 11 and having a hole 19 centrally. located therein. Connecting this opening 19 with an opening 20 in a ring 21, which is formed in spider 18, is a sheet metal casing 22 of tapered form, and to the lower end of-ring 21 a sheet metal discharge spout 23 is secured.

Secured upon the lower end of the fan shaft and impinging against the screen 17, is a brush 10, which has a series of tangential blades 31, which are adapted to contact with thescreen 17 andtokeep it cleaned.

Thus between casing 1 and ring 12, I have provided an annular space 24 in which dirt may accumulate, and between ring 12 and casing 22 an annular space25 is also pro vided; for accumulation of dirt. In order to provide access to these spaces forpurposes of cleaning, I have provided a series of doors 26 in the bottomof the device,

which are mounted on hinges 27 formed in the edge of ring 21 and which are held closed by a series oflatches 28 which engage notches in the legs 3 of the device. J

I have found it desirable for certain purposes in the manufacture of the product produced by my improved cleaner, to spray the material falling through casing 23, very lightly with certain fluids, such as oil, and

for this purpose I have provided a sprayer head 29 at theend of a pipe 30 extending I through casing 1, ring 12 and casing 22.

In the operation of my. improved cleaner the fiber to be cleaned, is blown through pipe 1 1 in separated condition. As it enters cage 9 the material impinges fan 8, the force of the blast causing the fan to rotate rapidly and to beat the separated material so that the heavieridirt therein becomes loosened from the fibrous material and is knocked through the space between the bars of cage 9 and into the space between the cage and easing through which it falls into the dirt collecting space 24 at the bottom of the casing. The lighter and partially cleaned material within the cage 9 is then blown to the bottom thereof where it strikes cone 15 and is deflected thereby to its periphery, a large portion of the air passing 45 j and spaced from the Walls, a beater mounted 7 from the device through screen a at the top.

The material then is blown onto and across screen 17, the remaining dirt falling into space 25. After havin been completely cleaned, the material passes into casing 22 Where it is sprayed as it drops from the dis charge spout. The removal of the dirt from spaces 24 and 25 is accomplished from time i to time by opening doors 26.

Having thus described my invention, what I claim is v a 1. In a fiber cleaner the combination or a casing, a cage Within and spaced fromthe Walls of the casing, a beater mounted revolubly in top of the casing and an air pipe projecting through the casing and the cage and adapted to discharge a current of air and the fiber against the beater so as to cause it to revolve and beat the fiber.

2. In a fiber cleaner the combination of a casing with imperforate Walls, a cage Within and spaced from the Walls, a heater mounted revolubly in the top of the casing,

a screen'in the bottom of the casing and having a discharge opening in" it, a deflector located above the opening in the screen and beneath the beater and anfair pipe projecting through the walls of the casing'and the cage and adapted 'to direct a current of air and the fiber against the heater and against the Walls of the casing to; bethencedeflected across the screen.

3. In a fiber cleaner the combination of revolubly in the top of the cage, a screen in the bottom of the cageand havlnga central openlng, a discharge tube leading from theopening through the bottom of the casing, a deflector Within the cage above the opening in the screen an air pipe adapted to direct. a current of air and the fiber against the heater and a spray. beneath the deflector and adapted to direct a spray into the opening.

5. A cleaner for fiber consisting of a casing,; a cage Within the casing and spaced therefrom, meansfor knocking the material to be cleaned against the sides of the cage, and a discharge spout adapted to permit the cleaned material to pass from thecage.

6. A cleaner for fiber consisting of a casing, a cage located Within the casing and spaced therefrom, a feed pipe entering the casing and the cage, a bafiie Within the cage, a removableclosure for the bottom of the space between the cage and casing, and a discharge opening at the bottom of the cage.

7. A cleaner for fiber consisting of a casing, a cage Within the casing and having the walls thereof spaced from the casing,a screen forming the bottom of the cage and fiber discharge opening, and means adapted to beat the fiber against the bars of the cage and against the screen.

S; A cleaner for fiber, consisting of a casing, a cage within'the casin and having the Walls thereof spaced from the Walls of the casing, a fan in the top of thecage, a baliie plate in the bottom of the cage, a screen in the bottom of the cage beneath the baffle plate and spaced from the bottom of the casing, the cage having an inlet opening therein in the path of the fan and a discharge opening therein beneath the bafiie plate. 9. cleaner for fiber, consisting of a casing, a cage Within the casing and having the Walls thereof spaced from the Walls of the casing, a fan in the top of the cage, a

screen in thefbottom of the cage and havber, 1919.
